ORNAM ENTAL CHAIN.

SPECIFICATION forming part of Letters Patent No. 311,114, dated January20, 1885.

Application filed September 8, 1884. (No model.)

To all whom it may concern:

Be it known that we, BENJAMIN S. FREE- MAN, Jr., and EDWIN L. ROBINSON,of Attleborough Falls, in the county of Bristol and State ofMassachusetts, have invented an Improvement in Ornamental Chains, ofwhich the following is a specification.

Our invention relates to an improvement in the construction of what areknown as roller-chains, and it consists in the peculiar and novelconstruction of the edge units of the chain, as hereinafter set forth.

Figure 1 is an elevation and partial section of the chain provided withour improvement. Fig. 2 is a plan view of the edge unit as formed forthe reception of the connecting bars or staples of the chain. Fig. 3 isan edge elevation of the same. Fig. 4 is a section taken in the line 00a: of Fig. 2. detail views.

In the drawings, A A are the center beads of the chain, which are formedand arranged in the chain in the usual manner. B B are the wire staples,which serve to secure the beads A in parallel rows of alternating beads,as shown in Fig. 1.

To form the edge units 0 of the chain we strike up a cup, at, having atone side of its edge a projecting plate, b, provided with perforations c0, adapted to receive the wire of the staples, and the opposite edge ofthe cup is provided with the projecting lip d.

To form the chain we first pass the staples B through the perforations cc,as shown in Fig. 5, and then turn the cup a over the plate I), asshown in Fig. 6, and secure the cup a Figs. 5, 6, and 7 are and plate bin their closed position by bending the lip (1 over the edge of theplate, as shown in Fig. 7. After arranging the center beads, A, upon thewire staples B, as usual, the 0 attached units 0 forming one edge of thechain,

we pass the projecting ends of the staples through the perforations c cof the plate I), and after lapping the ends of the wire staples over theface of the plate close the cups upon 5 the plates to form the oppositeedge of the chain.

Instead of the perforations c c in the plate b, equivalent open notchesmay be employed, as common in such chains; but our invention differsfrom all previous inventions of this class by reason of the formation ofeach of the edge units of the chain in one piece, with consequenteconomy in the manufacture of such chains.

WVe claim as our invention- 1. The improved edge unit for an ornamentalchain, consisting of the cup, perforated or notched plate, andfastening-lip, made integral with each other, substantially asdescribed.

2. In an ornamental chain, the combination of the central beads or linksand the connecting-staples with the integral edge units, constructed andarranged substantially as described.
